“The optogate phantom power line tester and the pink noise generator are ideally suited for applications on stage and in front of it. Anyone insisting on useful tools will love it. Totally recommendable. With both test candidates, a line check is far quicker and equally reliable. The visual and acoustic indications ensure a quick and reliable operation on stage - an absolute advantage.”
